Specifications

H. Wheel Hub Assembly
1.
Assemble the wheel bearing cups and the outer
axle shaft drive studs to the wheel hub.
2. On disc style wheel hubs:
Press wheel studs into place. Left thread studs
go into the left hand hub, right hand thread studs
into the right hub.
On cast spoke style hubs:
Assemble the brake drum to the cast spoke
hub and secure with bolts, washers, and nuts.
Tighten bolts to correct torque. Install the rim
studs to cast spoke hub.
3.
Pack the inner wheel bearing cone with the
proper lubricant and insert into the wheel hub.
4. Coat the outside circumference of the wheel hub
seal with liquid sealant and press into the hub.
5. Pack the cavity between the inner and outer
wheel bearing to the level of the small diameter
of the bearing cups.
6.
On disc style hubs:
Adjust the brakes to match closely, but still
clear, the brake drum.
On cast spoke hubs:
Adjust the brakes to match the brake drum by
using a brake shoe adjusting gauge. Measure
the I.D. of the drum and adjust the brakes to
match the gauge reading. The gauge is
available from the McMaster-Carr Supply Co.,
Los Angeles.
7.
Postion the wheel hub or cast spoke hub and
drum carefully over the spindle, brake and spindle
yoke assembly. (See fig. 17, Page 10.) Rotate the
hub while positioning over spindle.
8.
Pack the outer wheel bearing and install over the
spindle.
9.
10.
Install the wheel bearing adjusting nut with dowel,
if used, dowel facing outward (or up). (See fig. 16,
Page 10.)
Adjust the wheel bearings per Ill-B. (Page 5.)
I. Outer Drive Yoke and Outer Drive
Axle Shaft Assembly
1.
The outer drive yoke should be complete with a
bearing race pressed on its hub. This race
should not have been removed at disassembly
unless either the yoke or race were replaced by
new parts.
2.
Lubricate the seal and bearing surface of the
outer drive yoke and put the yoke in place in the
bearing and seal that is in the spindle yoke. (See
fig. 37).
3.
4.
Apply a bead of liquid sealant to the outer axle
shaft flange. (See Service Bulletin 738 407, Page
22.)
For the SDA-12.
Install the yoke spacer ring onto the outer axle
shaft splines. Insert the shaft into the spindle
bore, rotate and align the splines with the drive
yoke splines, rotate the shaft and yoke to align the
flange holes with the drive studs. Insert the yoke
retaining bolt through a new sealing washer,
through the retaining washer and into the
threaded hole in the shaft end. Tighten to
specified torque.
5.
Push axially on the outer drive yoke and check for
positive clearance under the axle shaft flange. The
clearance should be at least .015-inch. (See fig. 40,
Page 19.)
6.
Install the locknuts to retain the axle shaft.
Tighten to the specified torque.
7.
On oil lubricated wheel bearings, turn wheel hub
to position the oil plug hole in the outer axle shaft
horizontally. (See fig. 41, Page 19.) Fill hub with
specified oil, install plug.
8. Install the hub cap.
